Today I came across something you don’t see very often anymore a traveling knife sharpener working from a modified motorcycle. It felt like stepping back in time. Instead of a shop or a van full of expensive equipment, everything he needed fit on his bike.
His setup was simple, but it clearly worked. For repairing chipped or damaged edges, he used a stone grinding wheel. Most of the sharpening was done on a sandpaper flap wheel, and he finished each knife on an old 2×32-inch belt that had obviously been used for years. It wasn’t pretty, but it still got the job done.

Incredible but true. This guy at least has a motorbike, the ones I used to see in my neighbourhood when I was young were just bicycles: https://previews.123rf.com/images/ermess/ermess1109/ermess110900027/20738068-bicicleta-de-afilador-ambulante-tanto-de-transporte-y-suministro-de-energ%C3%ADa-para-su-trabajo-est%C3%A1n-decora.jpg
Awesome!! This was very common, and served the community well!
